  1. Summary of the session Interoperability and Resource Utilisation Cécile Germain-Renaud Claudio Grandi

  2. Introduction • Many infrastructures are providing resources for e-science • Local resources, regional and disciplinary grids • Resource integration at the European scale is required • A fully integrated (“monolithic”) grid is not a realistic perspective • Interoperability & interoperation • Standardization • Access to heterogeneous infrastructures • Application-level abstractions Claudio Grandi - 3rd User Forum - Clermont-Ferrand - 14/2/2008

  3. EGEE strategy towards interoperability: The best solution is to have common interfacesthrough the development and adoption of standards. The gLite reference forum for standardization activities is the Open Grid Forum Many contributions (e.g. OGSA-AUTH, BES, JSDL, new GLUE-WG, UR, RUS, SAGA, INFOD, NM, …) Problems: Infrastructures are already in production Standards are still in evolution and often underspecified OGF-GIN follows a pragmatic approach balance between application needs vs. technology push GIN Standards Claudio Grandi - 3rd User Forum - Clermont-Ferrand - 14/2/2008

  4. Interoperability Claudio Grandi - 3rd User Forum - Clermont-Ferrand - 14/2/2008 How to achieve interoperability in absence of adequate standards: • Parallel Infrastructures • User driven: the user joins different grids (uses different tools) • Site driven: the site offers different access methods to resources • Gateways • Bridges between infrastructures • Adaptors and translators • Single API for users. Plug-ins provide translation

  5. Interoperability models By L.Field Gateways Gateway User driven parallel infr. Site driven parallel infr. Adaptors and Translators Plugin API Plugin Claudio Grandi - 3rd User Forum - Clermont-Ferrand - 14/2/2008

  6. SAGA API for gLite Service Discovery • Steve Fisher presented the work done within EGEE-II to support the OGF-SAGA APIs in the gLite service discovery • Motivation for Service Discovery • Middleware has to dynamically find other services • Users need to be able to “bootstrap” the environment when travelling (i.e. at different locations) • Use SQL-like filters to search resources • GLUE 2 compatible • SAGA specific code will go to the OGF repository • BDII and RGMA code will go to the gLite repository Claudio Grandi - 3rd User Forum - Clermont-Ferrand - 14/2/2008

  8. Towards a WBEM-based Implementation of the OGF GLUE Information Model • Sergio Andreozzi presented the work done in OMII-EU to design GLUE 2.0 and information providers based on WEBEM standard by DMTF • How do we describe resources shared in Grid systems in order to enable: • Resource awareness • Resource discoverability • Resource requirements expression • Resource monitoring • Currently in gLite 3: • Information Model (IM): GLUE 1.3 • Concrete Data Model (CM): LDAP • Information Providers (IP): Any language that write ldif files • Information Provider Manager (IPM): OpenLDAP Claudio Grandi - 3rd User Forum - Clermont-Ferrand - 14/2/2008

  10. An Application of ETICS Co-Scheduling Mechanism to Interoperability and Compliance Validation of Grid Services • Carlos Sanchez presented the work done in ETICS to produce an automated facility to reproduce real scenarios under fully controlled environment • General purpose: to run functional and conformance tests on production-like scenarios • Prototype produced that verifies BES compliance of the CREAM Compute Element (in collaboration with OMII-EU) • Develop the test suite that interprets and parses the recommendation into specific service calls • Use or develop the independent client which will perform the test • Will repeat the exercise with the OGSABES extensions for UNICORE Claudio Grandi - 3rd User Forum - Clermont-Ferrand - 14/2/2008

  11. Claudio Grandi - 3rd User Forum - Clermont-Ferrand - 14/2/2008

  12. gCube Grid Services • Pedro Andrade presented gCube • Collaborative framework built on DILIGENT software • Not only resources and data but also applications to access the data are managed • Virtual Research Environments (VREs) are collaborative environments created on-demand through remote sharing of resourcesto support the research activities of distributed communities • gCube provides a vast number of VRE services for Content Management, Workflow Management, Information Retrieval, VREs Management, etc. • The creation, management and exploitation of VREs using gCube has been successfully tested in DILIGENT • A new VO can join the infrastructure in less then 1 day • A new VRE can be deployed in less then 2 hours Claudio Grandi - 3rd User Forum - Clermont-Ferrand - 14/2/2008

  13. Claudio Grandi - 3rd User Forum - Clermont-Ferrand - 14/2/2008

  14. A simple SPAGO implementation enabling the connection of heterogeneous computational resources to a gLite based GRID • Andrea Santoro presented SPAGO (Shared Proxy Approach for GRID Objects) • Motivations: • Grant access via grid to resources not on the standard SL/IA32/x86-64 platforms • Implemented on the ENEA AIX cluster using LSF and AFS • New simpler solution based on ssh and NF • Deal with limiting firewall settings • Doesn’t require specific WN installations • Requirements to gLite • Provide a mechanism to inform users that the site is somehow ‘special’ and may not provide all the features of a normal site • Pay attention to architecture-dependent gLite modules on WNs • Define if they can run on a proxy Claudio Grandi - 3rd User Forum - Clermont-Ferrand - 14/2/2008

  16. INTERCONNECTING GRID, DESKTOP GRID AND NETWORK • Kostas Georgakopoulos presented a project pf the University of Macedonia to connect Condor pools and BOINC infrastructures to EGEE using a gateway-like approach • Main issues to be solved are related to the security • No control over “malicious” PC owners • Still not able to exploit the Condor “Standard Universe” • Next steps • Exploit desktop in schools of north Greece (~65000) • Integrate with the Berkeley Open Infrastructure for Network Computing (BOINC) • Open source platform for creating scientific distributed projects modeled after the SETI@Home project Claudio Grandi - 3rd User Forum - Clermont-Ferrand - 14/2/2008

  17. Claudio Grandi - 3rd User Forum - Clermont-Ferrand - 14/2/2008

  18. Partnership for Advanced Computing in Europe (PRACE) • Per Österpresented the PRACE project • PRACE started on 1/1/08 and has members from 14 European countries • Prepare creation of a persistent pan-European High Performance Computing (HPC) service • Provide European researchers with world-class computing resources • Establish the top-level of the European HPC ecosystem involving national, regional and topical HPC centres • Deploy several leadership systems at selected tier-0 centres • Contribute and use standards, in particular following the work done for gLite-UNICORE interoperability Claudio Grandi - 3rd User Forum - Clermont-Ferrand - 14/2/2008
